Vaz = 16 m ^ 3.
Vkis = 14 m ^ 3.
ρaz = 1.25 kg / m ^ 3.
ρkis = 1.42 kg / m ^ 3.
maz -?
mkis -?
Let us express the mass of gases by the formula: ρ = m / V.
m = ρ * V.
maz = ρaz * Vaz.
mkis = ρkis * Vkis.
maz = 1.25 kg / m ^ 3 * 16 m ^ 3 = 20 kg.
mkis = 1.42 kg / m ^ 3 * 14 m ^ 3 = 19.88 kg.
Answer: the mass of nitrogen maz = 20 k is greater than the mass of oxygen mkis = 19.88 kg.
